excessive foam on top of wort even after a few days of flocculation

[slobrewer85]

I have a batch of red ale that is 7 days into fermentation. Everything has slowed down and I used a liquid london yeast starter, which is a medium flocculator. There is about a half inch of thick foam (not the aerated bubbly kind that I am used to) on top and it doesn't seem to be decreasing very much in volume. Has anyone else experienced this before? It smells great. I am always paranoid when something out of the norm happens around this time in the fermentation process.

it's fine, it may stay there for a long time. follow your gravity readings.
